Hi,

I use SpecialSlots to show saturdays with a blue background and sundays with a red background.
That works in Month and Day view. But in my horizontal TimelineView set to VisibleDays = 7 the background does not change at all.

Regards,
Håkan

Hi Håkan,

This is a very strange behavior. Is it possible to send us sample running project or the StyleSelector that you use to test it locally?

Hi Rosi.

I can't send you a project since it is part of a huge application, but I can send you some bits and pieces.
Tell me if you need more.

public class CustomSpecialSlotStyleSelector : ScheduleViewStyleSelector
{
    public Style DefaultStyle { get; set; }
    public Style ReadOnlyStyle { get; set; }
    public Style SaturdayStyle { get; set; }
    public Style SundayStyle { get; set; }
 
    public override Style SelectStyle(object item, DependencyObject container, ViewDefinitionBase activeViewDefinition)
    {
        if (item is DefaultOccurence)
            return this.DefaultStyle;
        else if (item is ReadOnlyOccurence)
            return this.ReadOnlyStyle;
        else if (item is SundayOccurence)
            return this.SundayStyle;
        else if (item is SaturdayOccurence)
            return this.SaturdayStyle;
        return base.SelectStyle(item, container, activeViewDefinition);
    }
}
 
public class DefaultOccurence : Slot
{
    public override Slot Copy()
    {
        return new DefaultOccurence()
        {
            Start = this.Start,
            End = this.End,
            RecurrencePattern = this.RecurrencePattern.Copy()
        };
    }
}
 
public class ReadOnlyOccurence : Slot
{
    public override Slot Copy()
    {
        return new ReadOnlyOccurence()
        {
            Start = this.Start,
            End = this.End,
            IsReadOnly = true,
            RecurrencePattern = this.RecurrencePattern.Copy()
        };
    }
}
 
public class SaturdayOccurence : Slot
{
    public override Slot Copy()
    {
        return new SaturdayOccurence()
        {
            Start = this.Start,
            End = this.End,
            RecurrencePattern = this.RecurrencePattern.Copy()
        };
    }
}
 
public class SundayOccurence : Slot
{
    public override Slot Copy()
    {
        return new SundayOccurence()
        {
            Start = this.Start,
            End = this.End,
            RecurrencePattern = this.RecurrencePattern.Copy()
        };
    }

Hello Håkan,

Please find attached sample project based on your code that works as expected. I suggest you try it and find the differences at your side.

Hello Rosi,

Your project containd resources that are commented out in the constructor of the MainPage.
I use resources, so I tried to uncomment your code, and then I get the same problem as in my project.

Could you verify that on your side that you can use special slots in TimelineView with resource grouping?

Regards,
Håkan
